To all whom it may concern:

Be it known that 1, Dave) ltosiin, a Cltilr zen of the United States, residing in Phi la delphia, Pennsylvania, have invented certain Improvements in Collar Buttons, of which the following is a specification.

My invention relates to that type of collar button which has a head provided with anti-friction means for facilitating passage of the band of a necktie to an fro over the same, the object of my invention being to so construct such a collar button that the presence of the anti-friction device will not interfere with the ready application of the button to or its removal from the buttonhole in the neckband or collar.

This object I attain in the manner hereinafter set forth, reference being had to the accompanying drawing, in whieh- Figure l is a top view of a collar button constructed in accordance with my invention' Fig. 2 is a side view of the same partly in section 011 the line 22, Fig. 1;

Fig. 3 is a side view partly in section on the line 3-3, Fig. 1;

Fig. 4 is a side view showing the head of the button adjusted for passing through the button hole in the neck band or collar; and

Fig. 5 is a view similar to part of Fig. 3 but on a larger scale.

In the drawing, 1 represents the base of the button and 2 the shank projecting from i the same. These may be of the usual construction, my invention relating to the head 3 of the button and to the means for mount ing the same upon the shank. The head comprises an elongated cup-like structure 4, with pointed ends 5 which are provided with inwardly projecting studs 6 entering openings in the opposite ends of an anti-friction roller 7. This roller 7 is of substantially the same shape as the cup 4 and it is disposed partlv within and partly beyond the edge of said cup. The studs 6 serve as pivots on which the roller 7 turns so as to facilitate the free movement over the same of the band of the necktie in effecting proper adjustment of the latter after it has been properly knotted.

The base of the cup 4 is slotted, as shown at 11, in Fig. 5, for the reception of the shank 2 of the button, and said base has, on opposite sides of the slot, segmental pockets 12 for the reception ofpins 8 which pro Specification of Letters Patent.

ject in opposite directions end of said shank, as shown in Fig. 2gthese pins providing a pivotal mounting for the head 3 of the button so as to permit the same to be turned to a position parallel with the shank, as shown in 4, in order to render easy the passage of the head of the button through the button hole in the neck band or collar, the pointed forward end 5 of the head readily entering said button hole and the tapering of the head from end to center assuring a gradual spread of the button hole as the head is passed throughthe same.

In order to normally retain the head of the button. in position at right angle to the shank, that portion of the shank 2 between the pivot pins 8 has a squared or shouldered upper face 9, as best shown in Fig. 5, which face bears against a spring plate 10 secured in the bottom of the cup 4, as shown in Fig. 3.

While the bearing of the spring plate 10 upon the shoulders 9, is sulhcient to retain the head of the button in its normal relation to the shank and base, as shown in Figs. 1, 2 and 3, it does not prevent the ready turning of the head on the pivot pins 8 to the position shown in Fig. 4 so as to be presented point first to the button hole in the neck band or collar, in applying or ren'ioving the button.

The pivoting of the roller 7 upon studs integral with the cup 4: of the button head cheapens and facilitates manufacture by reducing the number of separate parts contained in the button.

I claim:

1. A collar button having an elongated head, a shank upon which said head is pivotally mounted so that it may be swung into line therewith, and an anti-friction roller mounted in said head and having its axis transverse to that of the pivotal mounting of the head.

2. A collar button having, in combination, an elongated head consisting of a cup with inwardly extending studs at its opposite ends, an anti-friction roller extending from end to end of said cup and having end openings for the reception of said studs, and a shank upon which said head is pivotally mounted so as to be swung into line therewith.

A collar button having an elongated head with pointed end, a shank upon which from the upper roller rotatably mounted therein and having its axis extending longitudinally of the head, a shank having at its upper end oppositely projecting pivot studs and an in termediate shouldered portion, bearings in the back of the head for said pivot studs, and a spring plate carried by said head and bearing upon said shouldered portion of the shank.

In testimony whereof I have signed my name to this specification.
